This invention relates to an improved coffee potembodying an arrangementof features cooperating to make drip coffee in a more satisfactory anddesirable manner than can be accomplished with the present daypercolators.

It is nerally conceded that to make good coiee 1t must not be boiled. Ingeneral, when coffee is made with the present day 1o marketed urns andpots, it is continuously boiled, thus making it unduly strong andfrequently distasteful. It has been recently discovered by'a plicantthat excellent colee may be made y simply dripping boiling water overthe ground colee, not allowing the coffee grounds tomi; with the madecoHee. With the foregoing thought in mind, I have evolved and producedsimplified structure which wiil cause the hot water to drip slowly uponthe ground coEee in a foraminous container and to accumulate insaidcompartment which is arranged apart from the main chamber and whereinthe main chamber is so constructedras to maintain a pre- 2-5 determinednantity of water to prevent the pot from un uly burning, yet retainingsufficient heat within the container to keep the coffee in its separatechamber warm.

The particular details for accomplishing this improved result willbecome more readily apparent from the following description anddrawings.

In the drawings:

Figure 1 is a central vertical sectional view through a coffee potconstructed in accordance withthe present invention.

Figure 2 is a top plan view with the lid or cover removed.

Figure 3 is a contracted sectional and elevational view of the watercolumn elevating tubes and distributor.

Figure 4 is a perspective view of the coffee containing basket.

The coffee pot as seen in Figurel c0m- 5 forming the made coffeecompartment 11.

" prises a body portion 5 of appropriate con# The main water compartmentis indicated i reference character 17 designates a vent hole which underpredetermined conditions -is closed bv a valve 18. This valve is mountedon a ball crank 19, which in turn is ivotally molnted on the lower endortion o the tube an 1s top and this has a coupling 21 telescopicallyconnected with the upper end ofl the tube 14 and the horizontal branch22 that carries an overhan ing distributin a multip icity of waterdischarge ports. is head is arranged` over the wire basket 25 which isadapted to contain the coffee. The basket is seated on the supportinglug or ledges 26 and 27, and is provided with a hinged cover 28 and anoperating knob 29. The Leshaped sectionof the water delivering conduitor pipe is detachable to facilitate application or removal of the wirebasket.

By placing one or two cups of water in the pot, the float l20 will beacted on and will close the valve 18 over the port 17. When the waterbegins to boil, it will be elevated in the tube 14. and the L-shapedpipe and is caused to drip down on the ground coffee in the basket 25.This dripping action is comparativen ly slow and as the water passesthrough the co'ee in the basket, it obtains sufficient strength to make00d coffee, which is maintained in the cham er 11.

As the water is boiled in the chamber 12, it is elevated until the"level reaches the point to permit the float 2O to swing down and lopenthe valve 18. The body of water then dis-- charges continuously throughthe port 17 to i relieve resistance in the elevating conduit to preventburning out ofthe pot. At the same time, it generates sufficient heat inthe chamber- 12 to keep the chamber 11 warm and to maintain thecoieetherein in a good .condition. It is of course necessary that asuiiicient number of cups of water be placed in head 23, ca r ingVrovided with a ba 1 oat 20. A substantia ly L-shaped pipe is provided atthe l the chamber 12 to make the desired quantity of coffee in thechamber 11. It is to be observed that the basket is readily removable topermit it to be filled With coiee and to permit the grounds to beemptied. Then, too, the part-s of the conduit are bodily removable topermit thorough cleaning. Thus, the pot is quite sanitary and willfulfill the requirements of a domestic cooking appliance of this class.

Persons skilled in the art to which the invent-ion relates will be ableto obtain a clear understanding of the construction and features andadvantages by considering the descriptionin connection with thedrawings. Therefore a more lengthy description is believed to beunnecessary.

Minor changes in the` shape, size and rearrangement of features, comingWithin the field of invention claimed may be resorted to, in actualpractice if desired.

Vhat is claimed is:

As a new product of manufacture, an accessory for use in associationwith a coffee maker of the class described comprising a hollowconcavo-convexbase having Water in-4 let apertures, a tube rlsingvertically there-v from and provided with 'a vent port, a bell crankmounted on the tube below said port, a valve carried by one arm ofthebell crank andcooperable with said port, and a float carried by theremaining arm, a substantially L-shaped pipe having a vertical branchfitted telescopically and detachably yover the end portion of said tube,and a horizontally right angularly disposed apertured distributing headcarried by the horizontal branch of said L-shaped pipe.

In testimony whereof I aiiix my signature.
